Retractable smoked visor designed to fit Stein/Kask Super Plasma Treecare helmets. With the visor lowered there is enough room to accommodate sunglasses but they probably won't be required. The Kask visor is fully CE certified for use with safety helmets: approved according to EN 166 and complies with the resistance requirements for flame and chemical agents in accordance with EN 14458. The outer lens is coated with a special scratch resistance formula and has a anti-fog treatment on the inner surface.
